Example
The model with industrial CA grade enclosure and having under-speed duty and initial time delay with standard M30 sensor probe is as given below
RM E211-TD-CA-11-B30
Special Application
Speed switches for specific applications as below are
available. Please refer works for more details.
Special models are available for over
speed safety of hoist crane.
I) Crane Application :
Model with specific operation of output
relay for plugging duty application. The speed switch senses
the speed switch of the rotating object near zero speed and
switches of the reverse sequence supply connected to the
motor.
ii) Plugging Duty :
Special controller unit to take
inputs from multiple no. of probes are available for
monitoring multiple shaft machine. The unit has got a
single output relay which gives a signal if any of the sensors
stops giving pulses.
iii) Cable Winding Machine :
A very high precision (12 bitmicrocontroller) unit for measuring and display speed of a
bullet of high speed projectile launcher. The unit incorporates
a special optical / magnetic type sensor
iv) Defense Applications :
